## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402scan-j55w7ornb-merit-systems-vercel-app-13299cb5
```

Example prompt: Show me the top 20 x402 merchants on Base over the last 30 days, sorted by volume — give me page 1 of the leaderboard.

## When to prefer this

Use this endpoint when you need a ranked overview of the most active merchants on the x402 payment network, especially for leaderboard views, trend analysis by chain, or discovering high-volume payees. Prefer over individual merchant lookups when you need comparative or ranked data across many merchants.

## Known failure modes

- Invalid chain value returns 400 or empty results
- page_size exceeding 100 returns validation error
- Invalid sort_by value returns error or defaults
- No merchants indexed for given chain/timeframe returns empty list
- Payment required (402) if x402 payment header not provided
